ATC SCM20ASL Active Stand-Mount Loudspeakers (Limited Edition)

Description

SCM20ASL

The SCM20ASL Limited Edition is a 2-way active loudspeaker released to mark the beginning of ATC’s 50th Anniversary year.

This exclusive new model, limited to just 150 pairs, packs ATC’s finest transducer engineering and active loudspeaker technology into a compact sealed cabinet, finished to exceptional standards in a stunning high-gloss blue lacquer.

Complementing the cabinet, the front baffle is hand-upholstered in dark blue full-grain Napa leather.

SCM20ASL Limited Edition continues ATC’s philosophy of combining the best in-house loudspeaker drive units with matched on-board active amplification for optimal fidelity. The new model integrates a 2-way active system, previously only available in a floor standing model, into a smaller stand-mount cabinet.

The SCM20ASL Limited Edition features ATC’s proprietary 150 mm Super Linear mid-bass driver paired with a 25 mm S-Spec dual-suspension tweeter.

The bass driver operates in a 20-litre sealed cabinet and power is provided by on-board class A/B MOSFET power amplifiers, capable of delivering 200 W and 50 W continuous power to the bass and HF drivers respectively.

The loudspeaker crossovers are active, analogue 2nd order Linkwitz-Riley and an all-pass filter is included to optimise the phase response through the crossover region, resulting in far improved tonal balance and imaging.

Optional C4 Sub Mk2

Perfectly complimenting the SCM20ASL Limited Edition, both sonically and visually, the C4 Sub Mk2 Limited Edition brings professional quality sound engineering into your home. This subwoofer is designed and built without compromise and delivers new standards of clarity in the lowest four octaves, enhancing the audio experience for music and film devotees.
